Step 1
Design & Selection
We finalise your design and hand-pick the certified center stone.
Save 20%A radiant cut lab grown diamond over a hidden halo, on a band set with three parallel rows of pave running the length of the shoulders. The triple row is the point of difference here, most pave bands carry a single line of stones, and adding two more widens the band into a broad ribbon of diamond that balances a large centre stone instead of disappearing under it. Beneath the radiant a concealed halo lifts the stone and throws light back from the side, invisible when you look straight down. Every diamond is a laboratory grown diamond, identical in carbon structure, hardness and brilliance to a mined diamond, graded E colour and VVS2 clarity. Each ring is made to order in our own Surat workshop and ships with a free IGI certificate for the centre stone.
This ring is made to order in ten metal choices, so you can match it to jewellery you already wear.
All gold options are solid gold, never plated or filled. White gold is finished with rhodium for a bright white surface and turns the triple row into one continuous sheet of light. Yellow and rose gold keep the three rows visually separate, because the warm metal between them stays visible.
Choose your ring size at checkout. We make every size from US 3 to US 13, including half sizes, at no additional cost. If you are unsure of the size, order anyway and contact us after checkout, we will help you confirm it before the ring goes into production.
Want a single or double row instead of three, the pave stopped halfway around, the hidden halo removed, a different centre shape, engraving inside the shank, or a matching wedding band sized to sit against this wider band, we can make it. For any other customization request please contact us at https://mapplegems.com/pages/contact and we will quote it for you.
It is a shank set with three parallel lines of small diamonds running side by side rather than the single line used on a standard pave band. The result is a noticeably wider band with far more surface sparkle, and it is a common choice when the centre stone is large enough that a thin band would look out of proportion beneath it.
A hidden halo is a ring of small diamonds set horizontally around the basket underneath the centre stone, facing outward rather than upward. From directly above you do not see it, so the radiant keeps its clean rectangular outline. From the side and from the wearer's own eye level it catches light and lifts the stone visually.
Yes. A lab grown diamond is real diamond. It has the same carbon crystal structure, the same hardness of 10 on the Mohs scale, the same refractive index and the same fire and brilliance as a mined diamond. The only difference is that it was grown in a controlled laboratory over a few weeks instead of underground over billions of years. No jeweller can tell the difference by eye, only specialist equipment reading growth patterns can separate the two.
Within a limited range. There is more stone set metal to work around than on a single row band, so we would rather make the ring in the correct size from the start. If you are not certain of your size, contact us before ordering and we will help you measure, or we can leave a short plain section at the base of the shank to allow for future adjustment.
Yes. Every ring ships with a free IGI certificate for the centre stone. IGI is the International Gemological Institute, one of the largest independent diamond grading laboratories in the world. The certificate confirms the carat weight, the E colour grade, the VVS2 clarity grade and the laboratory grown origin. There is no extra charge for the certificate.
A radiant is a rectangular or square stone with cropped corners and brilliant style faceting. It combines the elegant outline of an emerald cut with the fire of a round brilliant, scattering light in many small bursts rather than the broad flashes of a step cut. The trimmed corners also make it more robust than a sharp cornered shape.
E colour is the second highest grade on the diamond colour scale and sits inside the colourless range, so the diamond looks bright white with no warm or yellow tint. VVS2 means very very slightly included, the second highest clarity tier. Any inclusions are so small that a trained grader needs 10x magnification to find them and they are completely invisible to the naked eye.
A lab grown diamond gives you a materially identical stone for a fraction of the price of a mined equivalent, which is what makes a 4 carat or 5 carat radiant centre realistic on a normal budget, and this setting is built for a large stone. Because the origin of every stone is documented from the moment it is grown, a lab grown diamond is conflict free by definition. Growing a diamond also avoids the open pit excavation, land disruption and water use that mining a comparable stone requires, so the environmental cost is considerably lower.
Mapple Gems is a made to order fine jewellery workshop based in Surat, India, the city that cuts and polishes the majority of the world's diamonds. We design and hand finish every lab grown diamond piece in house rather than reselling stock, which is why every ring on this store can be adjusted to the metal, carat weight and size you actually want. Our team works only with laboratory grown and certified stones, and every order is inspected and photographed before it leaves the workshop.
